Forgive me, but I think you may be getting bogged down in the detail.
If you are at the stage of 'considering building' then you are sufficiently far away from fitting radios that I can almost definitely say that regulations, your aspirations, and product availability may be very different by the time you are seriously looking at radio fitments!
I don't mean to be dismissive of your ambition, or wish to discourage you in any way. Aircraft construction is a truly laudable and praiseworthy endeavour.
It's also utterly beyond
my abilities and level of determination / persistence: I've settled for flying and maintaining one myself and restoring others with a friend.
Find a design you like the look of, fulfils your mission profile, fits your pocket, and go for it!
Details like avionics, instruments, colour, upholstery etc can all be decided later - and you will end up considering options for your skybound steed that you cannot imagine now!
