so I don’t need or want a CPL as far as I can see
I had considered CPL+CRI.
Why? The CRI does not need a CPL or CPL level knowledge. The CRI suits a niche market, where you have a specific purpose for doing it; teaching aerobatics, tailwheel conversions, differences training rental checkouts etc. If you intend to invest the time and effort doing an FI course, you don't need a CPL, but its severely limits what you can do if you don't invest in CPL level knowledge.
