Possibly the nearest perfect all around telescope would have thd be the Evolution series as it can converted to f2, f10 for planets, focal reducer for wider fields so a jack of all trades, but it does require a heavy duty more expensive mount
Maybe you should look to see why they use refractors, so many more advantages and in astrophotography unless planetary its not often about aperture, an f5 4 inch refractor will still have a shorter wider field, often Newtonians, unless modified may not be able to get enough focus. The defraction spikes can be bothersome. One of the best astrophotographers on You tube, Trevor Jones often uses a small 4" apo and even a 60mm and would not even know were done on a small aperture. With astrophotography light continues to gather and build up, unlike the eye. Also a bigger scope can give poor results due to atmosphere contains and a refractor often gives better steadier conditions. Beginners don't often grasp that in astrophotography its not always about aperture less important than for planets and visual, both totally different.
Also the bigger the scope the more beefy it needs to be and most costly. Also more likely effected by wind and collimation issues

Also if you have poor atmosphere conditions which is harder to achieve using a larger scope may have to bin your camera to get good results, so will cause you to have lower res and resolution so taking away the benefit of having a larger scope
You may also lose the benefit of a larger aperture as you get less good contains to use them, wereas a refractor is steadier and can be used more often than a reflector on poorer nights. If you use a larger aperture you may have to go to binning 2 or 3x so has an effect of dropping resoultion and sharpness so lose the advantage of using a bigger scope
