Since you mentioned a 4x5 that includes a rangefinder, are you planning on "quick" shooting ( handheld?), on a large negative ?
Or are you going to want / need camera movements (rise/fall; tilts, swings, etc)
for things like architectural photography ?
If your goals are the former (large format on-the-go), then a press camera is probably the way to go; if you're going Graphic, try to find one with a "Graflok" back - gives you more options for finding/using roll-film backs, polaroid adapters, etc.
The "down side" to the press camera are the limited camera movements: there are no "back movements" to correct the film plane, and the front movements are limited to rise & fall, and horizontal shift.
If you might be getting into architectural photography or landscape/wide-angle work, then you might want to consider a "field camera" or a mono-rail. Field cameras are comparatively light and designed for tracking into the wilds; mono-rails MUST be used with a tripod, are heavy and somewhat awkward to lug about, but offer the greatest flexibility in terms of camera movements, revolving backs, bellows extension, etc.
You can usually find a variety of mono-rails going cheaply on e-Bay; I got a 1960's Calumet 4x5 the other year for about $100; another $150 got me a very nice Kodak Ektar 152mm lens in a Supermatic shutter (ex-Graphic) from Midwest Photogrpahic Exch.
Cambo and Linhoff are other good makes of LF.
Then there are the lovely wooden field cameras - Wista, Tachihara, Burke & James, etc... newer ones are pricey; older ones can be ... pricey...
These have some of the view camera movements - usually rise & fall, tilt, swing, and shift on the front standard; and tilt, and shift on the rear standard; usually plenty for landscape, portaiture, gen'l use.
A good introductory book is "Using the view camera", by Steven Simmons.
Beware of "antique" cameras - they look great, but may need to have the bellows replaced, lens / shutter work, custom adapter made to accept modern film-holders, etc... all of which can be done, at a cost...
Good luck & good hunting !

Forgot to add - you can find nice individual rangefinders either from hunting outfitters (Nikon, Leitz) or e-bay : Kalart, Heydes, Leitz, and others - you could put it on a lanyard, or some have a shoe-mount to go on the camera.
