I'm not sharing /home, I used this as a bad example to simplify here...
I'll rephrase -- I'm sharing dir2 found at /dir1/dir2.  dir2 is owned by
root:wheel and set to 755.  There is a subdir /dir1/dir2/user within that
is owned by root:user set to 2770.  I can mount /dir1/dir2 with MacOS
Catalina and see the contents of /dir1/dir2/user, but cannot write -- get a
"read only filesystem" message.

Doesn't matter if I set /dir/dir2/user to 777, can mount, still can't write
with MacOS Catalina.  I've even tried mounting with mnt_sambafs -f 777 -d
777 ... and the mount works, but still have the same issue with writing
files.

I kinda suspect this is an issue on the Mac side... if this isn't the best
place to find a solution, any suggestions of other good Mac based listservs
to ask this type of question would be appreciated.
