I went through this same thing this year - flat-bar hybrid bikes for recreational riding, some dirt and gravel (no mtb, jumping etc), decent quality, good support. Actually got to try several bikes by buying used (and reselling for what I paid or more).
The one bike I could not take my eyes off of was the Marin DSX2. That 1x12, hydraulic braking, carbon fork; geometry and positioning seemed perfect. Alas, no dealers anywhere within a reasonable drive had any in stock, none popped up used, so I never did get to ride one.
I tried a Specialized Sirrus X 3. Quite a nice ride! but the geometry was a bit off for me. I wasn't super-impressed by the Microshift transmission, it was ok.
Rather than run through the others I tried, I finally settled on a Kona Dew Plus. Reasonably priced, good componentry, bike fit me perfectly and was a true pleasure to ride. I did manage to mangle the rear brake, and when I took it in for service the shop had a used Kona Dr. Dew, so we worked out a deal. The Dr. Dew is basically the same geometry, has a 1x12 vs the 1x10, great drivetrain, so-so brakes. It is
steel, and riding it is so much smoother than an aluminum-framed bike with a maybe 1-2lb weight penalty. Did a 30mi ride on it this weekend and at the end, felt I could easily go another 20-30mi, it's that comfortable and easy to pedal!
Contrary to popular belief, modestly wide tires do not slow you down - see
https://www.renehersecycles.com/why-wider-tires-are-not-slower/ for one explanation. They do improve the ride as they smooth out or absorb road/path irregularities. I am running 650x47b and according to my stats am using less effort on my weekday route than I did with 700x38mm or 700x42mm tires, and get extra comfort from the slightly lower psi.
