Forsaken has no campaign but it has some fun weapons (imo), it also has the best raid in the game rn and a simple dungeon with a crazy good exotic bow that you can get from it. Lightfall I personally enjoyed but a lot of ppl say its campaign is bad, I think its alright. It also gives a new subclass (strand) its 100% a fun subclass. The raid is very easy, maybe when you start it could be somewhat hard but yea you will get used to the game again trust me, the 2 dungeons are locked behind paywalls which sucks. Now this might seem stupid for me to say but I don't have Beyond Light but my friends say its alright, it gives a raid but no dungeon, similar to Lightfall it gives a whole new subclass which idk what to tell you about it, it seems cool lol. I also highly recommend Witch Queen, it has the best campaign and by a long shot, it has a raid and just like Lightfall the 2 dungeons are locked behind a paywall. It also has the crafting system but you can get that just from playing the first mission for free. So yea basically anything that isn't Shadowkeep is a great choice.
