I have a 160mm travel hardtail (Ragley Troof)… it’s a very blunt tool which only really comes to life when the going gets gnar… it takes a particular terrain and riding style to justify such a beast IMHO and MHE etc.
A 130/140mm travel hardtail like the Ragley Mmmbop I had before is a much more rounded entertainer… can do all the beast can but a little slower and with a bit more added mince.
Loads of frames out there to take this fork length… Cotic Befe/Ragley Blue-Pig/NS Surge/Orange Crush/Saracen Zen/Chameleon as suggested above. Ragley currently very cheap at CRC.
Forks with 15 or 20mm bolt through are a good idea… and a dropper post is a wonderful thing indeed for rolling terrain and maximising fun without having to stop to lower the seatpost… so worth checking your frame can take one (seatube of 30.9 or 31.6 for the best ones).
Enjoy!
