Great to see others struggling with similar problems ;-)

In my experience you really should avoid manual type registration and
start converting to "proper qml modules". This is quite some work but
the only way to ensure that tooling really sees the whole picture.

For the qml Code this is actually not so difficult. You might have a
look at https://github.com/njeisecke/qml-migration, this did save me
quite some time.

For the C++ code exposed to Qml there is probably more work to do,
because restructuring parts of the code base is likely required. Rule
of thumb is "one module: one directory, one CMakeLists.txt + uri must
follow source directory structure from project base". Im my experience
any derivation from that rule causes pain and suffering ;-) Or maybe I
still don't fully understand the IMPORTS, OPTIONAL_IMPORTS.
DEFAULT_IMPORTS, DEPENDENCIES. IMPORT_PATH. OUTPUT_TARGETS and
OUTPUT_DIRECTORY options of qt_add_qml_module.
