Larryzaur does comedy videos, as did DrakGamestein until I stopped watching (I just... stopped finding him funny? Or the people in his group I actually considered entertaining left). MTQ is guides (from what I know, last I looked up was her guide on E12S 'cause my ex-bf was having trouble visualizing Advanced Relativity).
NightSkyPrince is nice to watch, though he only recently got into XIV so he's fanboying a bit TOO much on ShB (to be fair, it IS considered the best storyline so far), so he mostly just played the MSQ on Twitch and uploaded highlights on youtube. I became aware of him because of Aerith's VA Briana White, who showcased some FF content creators.
It really depends on what you're looking for.
EDIT: Oh! EthysAsher for Lorecasts and Q&As, GamerEscape does Lorecasts every so often but Ethys is exclusively into Lore.
