Well, I have an LPL 4550XLG that I use to print 35mm, 645, 6x9 and 4x5 formats. I have the variable contrast color head that I use for black and white filtration. 50mm, 105mm and 135mm enlarging lenses cover all my formats. I don't print larger than 11x14 so far but the specs on this enlarger are that it will do 20x24 on the base.

If you are enlarging larger formats you'd need a bigger enlarger, of course.
