There is many and looking towards the curseforge 1.16.3 mods or Youtubers that have covered many mods is a good idea to start with, or try out a few modpacks. Though I don't like to recommend modpacks as someone that reviews them I find too many of the same popular ones are in there and if you don't like them it's hard to find packs without them so I find I make my own based on what I review and there is more variety/different stuff to expect. Just saying from my experience at least. I myself look at a range of mods niche/new and cover some that add recipes for Vanilla to tech, mobs, biomes and more. And just because they are niche/new doesn't mean they aren't fun it's just they are new to that version with few downloads rather than just a port of a mod across many that appeared on 1.16.3.
When many Youtubers cover the same ones people have heard of in the millions range I find it's a fine start but not a good idea as you only see a small few and have different expectations and not all dimension mods are filled with hundreds of weapons/mobs/dimensions like Divine RPG on there but instead other mods that fill in that gap in the 10000 downloads range that focus on 1 dimension, a powerful suit of armour/tools and fits in with Vanilla better or other mods your using and by new creators and not just waiting for a mod you like to be updated. Not trying to plug myself but if you want a good look at what comes out every day from a range of mods/mods on 1.14 to 1.16 versions I have some you can look to across a range of mod types (again, tech, mobs, food, biomes, tools/armour, recipes, etc.). https://www.youtube.com/channel/UCyiHWb7p9yxDH1vaYZPdo9w/playlists?view=50&sort=dd&shelf_id=3
