A lot of the mods I listed here are also on 1.16.5 You can use Curseforge to search mods and also download them which helps a ton in building your pack.
Best tech mods IMO are Immersive Engineering, Ticon, and maybe Mekanism. Thermal Expansion/Ender IO are fine but really overrated, and IC2 is fun and enjoyable but really badly designed. There's a couple great obscure tech mods out there if you're willing to do a little pioneering, though they usually take a little bit of extra CraftTweaker-ing to fit in nicely with the rest of your pack. I always personally enjoyed Pneumaticraft the most but I feel like it's more of a support mod than something you can build a pack around, which is great because it can safely fit into pretty much any pack anyway.
The most important thing in building a pack is maximizing the amount of things your community can do while minimizing bloat, complexity, and load time. You want people to have the tools to make their own fun instead of just railroading them down a pre-defined progression like some packs, or just throwing everything at them all at once with no consideration of balance and overwhelming them like most packs.
