ik this is a lot of mods but there are a lot of mods that are needed for complete optifine parity
you could also add mods like smooth boot (older than 1.19.4) and ferrite core
most of these mods are made for newer versions though so people who play on old versions would be missing out
and while your at it you can add sodium extra and reeses sodium options for more stuff for sodium itself
