I have a double iron door with two iron pressure plates triggering them. The pressure plates are right in front of the doors. Because of the nature of iron pressure plates, the doors close very quickly so unless I am running through them, the doors close in my face (as I step off the pressure plates). I have been trying to come up with a redstone circuit that opens the doors immediately but also delays the close so that I don't have to sprint through them every time.
This seemed like a simple setup until I tried and I am really getting stuck. I have built the really simple delayed circuit with 4 redstone dust and 2 comparators (can't think of what it's called) so I have that going for me but routing the power back to the doors, while also keeping everything hidden underground, has been difficult. I could really use some help on this. I'll upload pics of what I'm working on.
Pic one is of the inside of my house and 2 is of the outside. The outside has 4 wooden pressure plates that open the doors from there. I want everything to work together too.
You have the basic idea: one path direct from pressure plate to door for immediate opening and a second the keeps the door powered longer than the pressure plate alone. [Also, pressure plates next to the door blocks and RS-torches beneath seem an effective solution for the door end of the device.]
Possibly one of the other types might fit better in your space.
[The one you've built is generally called a Fader (or Comparator Fader) because the output signal strength decays over time (unless boosted – as by a repeater).]
It's a bit hard to see how much space you have to work with, but (in terms of 'hiding the works') it may be advantageous to carry the initial signal down several blocks to a 'utility room' where your build will be less constrained. [Downward facing sticky piston moving a redstone block at the end of a stack of slime blocks is simple and fairly compact.] The output would then be run back up to turn on the RS-torches that keep the doors open.

WARNING: I have an extemely "grindy" playstyle; YMMV — if this doesn't seem fun to you, mine what you can from it & bin the rest.
The problem I'm running into is that I've put a rs torch under my doors as you mentioned but when the torch gets toggled, it toggles the piston (I tried a system using a piston and an observer) and the circuit repeats over and over like a clock until I break it.
This isn't exactly what I'm trying to accomplish. I'm trying to keep the doors open for a slightly extended period (like a couple seconds) but also specifically with iron doors. Having iron pressure plates is where I'm having the problem because they shut off the circuit so fast.
I honestly don't think what I'm trying to accomplish is possible. Unless there's some weird redstone mechanic that isn't obvious. I'll post another image of the main issue and I'll try to describe it here: When I step on the iron pressure plate, the doors opens because it's next to the plate, which is good. The plate also activates the circuit underneath via the piston/redstone block or observer block (I've tried different methods). This circuit is what extends the redstone pulse and I want to link that back up to both doors but the issue comes in there. When I route the power back to the doors, I can't figure out a way to do it where it doesn't reactivate the piston and start the cycle over again. The doors just keep opening and closing once that happens. And through all of this, I want to keep the circuitry under the floor. Space is flexible, but that seems irrelevant if I can't even get past my main issue of repeating the cycle over and over.

Well, it isn't the prettiest circuit I ever made but I did get this working. Since heavy weighted pressure plates only activate 1 block below them I had to have 4 little power re-feeding loops, I color coded it to make it easier to understand. The white, gray, blue and yellow are all identical and the green is the line used to power the doors. Since powering the door with torches, like in your picture, would cause interference you'll notice I'm powering it with redstone dots beside the base of the blocks which will be covered by your walls. Hope this is all you need, good luck.
Edit: A little explanation- The pressure plate activates the redstone beneath it which passes the current down with torches to a repeater array where 1 repeater immediately powers the tower that controls the door while the other 2 pass the same signal to the same tower with enough delay to extend the signal. There are 2 door control towers (one for each door) being fed by 4 of these repeater arrays (1 for each pressure plate).
Wow, I feel so dumb. I spent hours trying to figure this out and I didn't even think to put a redstone dot next to the door. I was so focused on thinking it had to go under it... I was about to give up haha. Thanks for the help!! I really appreciate the effort you put in!

No problem, I think every redstoner has gotten tunnel vision working on a project at one time or another. Glad to help you get over the hurdle, have fun wiring.

The thing you created with the comparators is called a pulse extender and you can use more comparators to extend the pulse even longer.

The comparator device you built is one type of pulse extender (see https://minecraft.gamepedia.com/Pulse_circuit#Pulse_extender for a list that includes several others).
Possibly one of the other types might fit better in your space.

I made the solution for you, just place this folder into your saves and take a peek.
