On my Focusrite interface, I have my gain set at about 4 to 5 for my vocals and guitar input levels. It doesn't matter if it's my Rode condenser or my Shure SM58, I generally don't have to change the gain if I swap mics out.

The Focusrite preamps are good, plenty of available gain, so I think you'll be OK running just about any mic you want.

Let us know how it works.

You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
