Trails (not really in to jumps and drops) and also longer distance XC stuff and 50m + rides over the South Downs etc.
Sounds like you’d might be best off on a proper XC bike, rather than the sort of thing that’s called a “Trail bike” these days. It’s going to be more comfortable and efficient over longer distances, without the extra weight, burliness, fork girth and geometry tweaks that “trail” bikes have to tackle the kind of downhill tracks that have jumps and drops in them. I’ve read reviews of bikes like the Solaris that say it gets up stuff well and goes along fine, but where it really comes to life is above a certain speed, hammering downhill.
Do you want that sort of bike, or something that’s lively and engaging up and along as well?
And/or how much enthusiasm do you have for pushing your riding, seeking out harder, steeper stuff and riding it faster?
