If you're using xenodm (which you should be) then add the commands for conky & fvwm (along with any other programs you want to be started) to ~/.xsession, as per the SESSION PROGRAM section of xenodm(1).

Something like this should do:

conky &
exec fvwm

Note that the ampersand at the end of the line is only needed if the application doesn't return the prompt when run from the command line. Unnecessary forking can cause race conditions and conflicts.

If you're not using xenodm then add the commands to ~/.xinitrc instead. That will be read when startx is run.

There is a web portal for those: https://man.openbsd.org/

Always use the base system as much as possible. The ports aren't audited and so tend to be of lower quality; avoid them whenever possible.
