Bike geometry and riding position has a huge effect on comfort and aches.

Whatever bike you end up with make sure it is the correct size and that in addition to that the bike is fitted to you (by changing stem lengths, stem angles, seat height, seat position etc).

When I'm out riding I see far too many people with relatively expensive bikes that are riding in the wrong position or awkwardly that will just tire them early or worst case damage their bodies,

I think this combination would have a far better outcome for you than trying to determine the type of bike or discipline.

Then once that is all done get out and ride regulalry - 3+ times a week!
