Hail and Good Day fellow Azerothians,
I am a returning player, going to give classic fresh a go and planning to play alliance for a change (have historically been horde).
Feral (Bear) Druid
Warlock
Paladin (Prot / Holy)
I am hoping to make one of those 3 my main, and I am returning after a long absence. I have a lot of XP as a tank and am a very good player. But I am returning after not playing since Pandas were new, and with no friends left playing. So I need a class I will find groups / friends / guild easily with and be able to raid at least semi hardcore. I plan to watch videos from KArgoz, Ebbnflow, Moo, and every other mega tryhard I can find to “git gud”.
Thanks again for any and all help

Which game version are you playing? The Fresh realms this Thursday?
Assuming you are:
Feral is good while leveling and you have to be pretty sweaty at 60 to make them good (You will spend a lot of time in Gnomeregan farming Pummelers). If you don’t go the extra mile as a Feral you will just suck
Warlock gets a free 40 mount and later a discounted 60 mount which is big early on. Very boring in raids, mediocre in dungeons. Usually in demand as not many people play them.
Pally you will be forced to heal at 60 and play 5 minute/15minute buff whackamole while wearing a blue dress all of Classic. The good note is this time with Dual Spec you can offspec prot or ret outside of raid, but aside from being handed an extra 2H from raid don’t expect having raid gear for those specs
If what I just said sounds awful, welcome to Vanilla 
Undead warlock. Lifetap + cannibalize is BiS leveling.
Druid/Paladin = healer. Don’t be “one of those” guys and try to meme around on your meme spec. You can, but you’ll end up playing mostly alone.
Warlock is always a good pick
Your choice is warrior or mage.
