Is it best practice to only run iBGP between 2 routers running eBGP or is it best practice to run iBGP in conjunction with OSPF? (or some other IGP)

If the two eBGP routers are not directly connected (on the same subnet), then you will have to use an IGP so they can communicate.

They are directly connected to each other.  Currently they run iBGP but I've been thinking to also run OSPF but unsure if it's really needed.

If the two iBGP peers are directly connected, there's no reason to run an IGP for the iBGP peers to communicate.
