If you don't want 6x6, 6x7 or red windows, that narrows things down to mostly press cameras or the relatively modern Fuji 645 or 6x9 rangefinders. The Fujis have gotten somewhat expensive. If you go that route, there is even a 645z model with a zoom and autofocus. Mamiya press cameras are fairly inexpensive, given their extensive capabilities, but I have no experience with them. I have a Graflex Century Graphic with a late model 2x3 Graflex roll film back that has automatic counting and auto stop for lever winding. Cost me next to nothing. Mine came with a cheap Agnar 105mm lens taken from a folder, but I always use it stopped way down so it performs well. You can mount lots of lenses in shutters to such a camera. Most lenses have a depth of field scale, or you can use an app to calculate. I take depth of field scales as only a rough guide to maximum depth of field. If you are using medium format, you probably want to make big prints or high res files, so you may want to stop down more than such tables/apps recommend.
Also, given that your profile says you already shoot large format and weight is not an issue, you could consider a roll film back with auto-stop for a 4x5 view camera or press camera.
