I would do the preflight from paper.

I would announce my checklist completion for each point in the flight.

If you can memorize all that is needed then that should be acceptable.

As you progress to more complex aircraft and procedures you need to
establish a flow that works for you every time.

The big three flows for me a

(Whats Next...) Especially IFR, set up the radios, radials, listen to ATIS for
for whats next as soon as you have a spare moment.

Brief the approach (again IFR) I do it from the approach plate in exactly the same manner every time.

The really big one is GUMPS, do GUMPS on entering the pattern and again on Short final.

I belong to a club and routinely switch from a retractable to fixed gear airplanes.

I always do a "Gear down" when on final, in the fixed gear planes I add "and Bolted" ;-)

If it's high wing I actually visually LOOK at the gear leg.
