For the case where checksums are disabled, moving there the check on
control data makes sense.

Yeah, let's do stuff on a single cluster which has them only enabled,
as initializing a node is one of the most costly operations in TAP
tests. Checking that the server is stopped is definitely a must in my
opinion, and your addition about emulating corrupted blocks is a good
idea. I would personally vote for keeping a control file check within
the tests of pg_verify_checksums as that's cheap.
