That's the exact opposite of what bundles are good for. Essentially, a bundle allows you to store a stack's-worth of *mixed* items. For massive building projects, you're still going to need multiple chests...
As for example, I currently have one bundle containing one copy of each of my (zoomed-out) maps, a cartographer's table, a few blank maps, and a few sheets of paper; I can stick it in a chest at home (whether that's my main house, "my" house/workspace at the village i'm currently working on, some other outpost) if I'm going to be working in/around that location for a while, and then just grab the one bundle before setting off on an explore rather than having to juggle multiple inventory slots. Another bundle contains all the things I need to start planting trees/crops/etc at a new village/outpost: grass beet pumpkin and melon seeds, potatoes, carrots, sugar cane, saplings of All The Trees, a beehive, a moss block... Again, just takes up the one slot; and once I got everything planted and growing at the new village, I refilled it and stuck it back in my Exploration Prep chest. (lots of rabbits near my desert village; now that I've got the library built and librarians are starting to show up to work, my next project is going to be the animal barn... once i've rounded up some rabbits and started them breeding, i plan to stash planting-bundles at each house/outpost/village) When I'm caving/mining, I grab an empty bundle and stash my clock and a crafting table inside. As my inventory starts to fill up with loot, I can pull out the crafting table to consolidate metals etc, and I can stash things I only have a very small amount of (emeralds, string, glow-squid ink, etc) to free up slots for more loot. Especially since I don't yet have an ender chest on this world (and will probably never have a shulker box) it definitely makes things much more manageable...
Of course, but at least with bundles you can put away random trash you collected off mob kills or harvesting crops during that time you were building and save yourself some inventory slots.
You may not want to use the bones or gunpowder now, but in future you will want to, the purpose of bundles is to discourage wasting resources and therefore rewarding skillful or at least rational gameplay, which is an upside in my honest opinion.
As far as large building projects go, shulker boxes are a better fit for holding the resources for those because they do directly increase inventory space or allow you to keep more of the same item.
I really like copper, it is a nice decorative block and it makes a fantastic roofing material. Amethyst is interesting. I think that it is slightly to rare, but it is nice to have another purple building block because there are not to many purple building blocks. Spyglasses are also quite nice for long distance viewing and close up inspection. Bundles are going to be incredibly useful for me because I like to carry a few maps and they take up a fair bit of inventory space. Plus you could put 1/2 stack of golden carrots and 1/2 stack of steak in one bundle for use together. Lightning rods have a few other uses to apart from protecting wood, and wool buildings. You can use it for charged creepers, brown mooshrooms, nitwit to witch transformations, skeleton horses, and zombie pigmen spawning.

To Be Honest, Copper Was A Letdown
