Your fork was a tapered steerer 15mm thru axle with 45mm of rake, post mount brakes, and 395mm axle to crown.
You should list what you want to spend because forks can cost $200 or $600. No point in suggesting forks that are way above or below what you want.
The 15mm thru axle and post mount are more dated features, but there are workarounds for both since many(most?) name brand gravel forks now come with 12mm thru axle and flat mount.
There are forks with about 45mm of rake and about 395mm a-c length, which are the two important measurements to make the new fork have the same geometry as your current fork.
