Check out this community as well. There is a forum post for it that I’ll link for easy access.
Wyrmrest Community Project - Wyrmrest Accord - World of Warcraft Forums (blizzard.com)
There are people I remember there who tend to play a little earlier in the day. Granted, it’s a community centered around mostly RP; but you may be able to find some folks who are down to group with you for PvE content. And if nothing else it could afford you some connections and help you get to know many of the more active members of the community.
It tends to be a very busy Discord from what I remember, so keep that in mind in terms of your anxiety and the variety (and passion) of conversation you’ll see there. However, for what you’re looking for, I can’t think of a better place to start.
