The main advantage of mirrorless for IR is with full-spectrum conversions, where there is no internal IR filter installed and IR filters are used on the lens. With a DSLR you would be viewing and focusing through a very dark filter, but the mirrorless monitor will compensate. I have DSLR conversions with an internal filter and they work just fine. I don't worry about focus as I use a wide angle lens for IR and stop down to at least f8.
I had an Olympus Pen-F converted to full color conversion and never use a filter on the lens as there is no need as I see And I use a less expensive Olympus wide angle lens the lens has full range auto focus and I can use the setup as I would use any other camera I own it’s in the WB before shooting and in the post
