Two issues:

First issue is that it appears that you can't call qmake from command line.

Either there's a bug somewhere on the Mac Ventura, or I'm missing some 
detail. I tried to build the Qt5Pas library by submitting Qt5Pas.pro to 
Qt Designer. It generated correct x86_64 objects, and the generated 
framework contains a:

Qt5Pas: Mach-O 64-bit dynamically linked shared library x86_64

Just to understand what was going on, I then tried again with the 
command line options, passing qmake exactly the same parameters which Qt 
Designer used, and the result was the same error as before, with the tmp 
folder populated with arm64 object files. It would appear that qmake 
ignores the x86_64 switch when called from command line. If this is 
confirmed it would be good to update the wiki page.

Second issue.

Lazarus does not build with Qt. I have set the appropriate symlink in 
the /Library/Frameworks folder, but build of Lazarus fails with the 
error message:

ld: framework not found Qt5Pas

I have added /Library/Frameworks to the compiler paths 
(-FI/Library/Frameworks). Should I tell something to the linker too?

Thanks for any hint.
