I think the cleanest way is to diddle the /etc/paths.d structure. I have
PeterDaardsiMac:R pd$ ls /etc/paths.d
40-XQuartz R TeX clang8 gfortran
PeterDaardsiMac:R pd$ cat /etc/paths.d/gfortran
/usr/local/gfortran/bin
PeterDaardsiMac:R pd$ cat /etc/paths
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
and the latter would want to be /opt/gfortran/bin for 12.2 (I still have 8.2 for now).
Two things to note:
1. The directories in paths.d/* are added to those in /etc/paths in alphabetical order, so careful with older versions in /usr/local/bin.
2. You (probably) need to logout and back in for the changes to take effect in your Terminal windows.
Alternatively, you can twiddle the shell startup files (~/.profile /etc/profile /etc/bashrc ....) directly. The trouble I have with that, is that I never feel sure that I am doing it in the right place.

I found several pages with differing instructions. I found one in "support.apple.com" that recommended something that didn't work.[2]

I did "env" to get the current path, than appended ":/opt/gfortran/bin" to that and executed the revised "PATH=...:/opt/gfortran/bin export PATH". However, when I checked with "env" again, the change was not displayed. I rebooted with the same result.
