I was also a Mythic raider, along with M+ dungeons (20+).
Im not as opposed to the story now, the FFXIV story is pretty good if you take the time.

If you want to skip past the story quickly.
Boost a Job to level 80, (if you can afford it) - even if you decide you don't like it, you get a 100-150% XP boost for any other job lower level.
If you do like the job it makes getting through Story much faster to be over level.

I don't suggest a story skip, the game progressively teaches the basics of the game as you go up in content.
People that story skip, it is obvious when they get to raid level, not knowing fundamental indicators and/or mechanics.
Just Escape out of all the story dialog and cuts

End-game raids are Very fun. Even old raids synced are fun.
And you can get groups for them despite what some say.

FF raiding isn't about gear entirely like WoW, It is certainly nice to have the raid gear.
However, you can clear the entire raid set in crafted gear which can simply be bought from the market board.

There are no addons or filters like wow, rather than being added into groups, as long as you have the ilvl you simply fill into a party finder group posted.
I don't suggest a static early on while you learn FF raiding, you learn far more from using party finder.

FF raiding is more like M+ though, unlike Mythic raiding, there Is far more personal responsibility for getting through savage or ultamates.
But people are far more patient with people learning the fights as long as you are honest about your progression point.

FF raiding is far more fun, and much less stressful compared to wow raiding.
PF has gotten far more toxic with how many wow players now play FF,
Many think they are better players than they actually are, or just in a rush for no real reason.

The current tier will be current for quite some time, you have until next summer to clear it.
And there are always groups clearing current content, many of them fill with Experienced players that want to teach newer raiders.
(I have been playing FF for 3 years now)
