So optifine is known for certain things like dynamic lighting and zoom, and given that optifine is now banned 1.16+, are there any mods that are allowed as a replacement for these?

Officially, I've never actually beaten minecraft solo, but on many servers I have. Every time a survival server that looks fun opens up, my friends and I team up to beat the dragon first. So while I'm not at all good at minecraft, I'm confident I can get better.
