The only times I ever ran out of content in WoW–been playing since 2004–was the six months or so before the next expansion’s prepatch. Even in the notorious 6.1 “Twitter integration” patch that didn’t add a raid, I still was happily messing around with my garrisons and collecting battle pets and mounts. If I weren’t doing the tourism thing now, I’d still spend hours upon hours with the new professions system. I spent more time messing with that in Dragonflight than I did in dungeons and raids.

Maybe you’re the kind of player that doesn’t roll alts? Just that alone is a lot of different content and different takes on existing content.
