When I opened Crossover 19.0.0.32195 in Mojave (10.14.6), I got the 'This app is not optimized for your Mac and needs to be updated' message.
The update for Catalina is in progress i guess
These warnings persist on Mojave because CrossOver still uses 32-bit wine with Mojave (since 32-bit support still exists there). If CrossOver used the same wine version for Catalina, it indeed would not work as the warning states. However, if a user is actually on Catalina, CrossOver will switch to the appropriate 32-on-64 bit wine which is compatible with Catalina.
I think the warning on Mojave assumed that the program would try to run in Catalina identically (which wouldn't work), but CrossOver has logic to run differently in Catalina from Mojave (which the Apple warning doesn't know).
I hope this clears up the confusion.
Thanks,

I would also add that I saw the same thing under Mojave and was hesitant to look at Catalina. But I can confirm in my own experience in a "real world" field test, after cloning my Mojave drive, updating it and doing some testing, that even though Apple and applications like 'Go64' still flag Crossover 19 as not being 64-bit, it works fine with Catalina. Even under Catalina I get those warnings, but it works. I assume it's the unusual nature of the 32-on-64 bit work that "confuses" it since that software was not programmed to expect such a thing.
