Medieval and renaissance are 2 separate eras of music. I think you might be specifically referring to wanting renaissance music if my guestimation is correct. Medieval was pretty much Gregorian Chant . Also your best bet is to study and analyze the sheet music of Renaissance composers which there is plenty of them on imslp. So if I were you I would google " renaissance composers" or "The Most Famous Renaissance Composers" Then YouTube their music and find pieces you like . Then search for those piece's sheet music on imslp.org which they have plenty of. Then follow along. Then print the sheet music out get a pencil and go through chord to chord and write them down and you will have the direct answer to your question from actual music from that era, rather than a general answer you'd get from other people. It's not really as simple as abc when it comes to specific progressions of that era. I'm also assuming you know enough about Music Theory to do that. I also say to do this yourself because you learn a lot better that way and get a better "Bag of Tricks" The Benefits are much better doing the work yourself, for yourself. Also if it feels like it's to much just start doing only a few measures at a time. Or listen to the music to listen for phrases and cadences and just analyze those 1 at a time. Also Instrumentation is half the battle here. Compose with renaissance instruments and you'll sound like that type of music already. I hope this helps. P.S. This goes for any era of music or genre or style whatever you want.
