How do you distribute your podcast on YouTube?

Hi everyone! I recently started a podcast, I'm using Spotify for Creators as a host and distributing it on Spotify and Apple podcasts via the RSS. On YouTube, I have been just manually creating a video with my episodes audio and a static image and uploaded it on YouTube. However I've noticed that YouTube too can distribute with the RSS, and wlit automatically turns the episode in video using the image uploaded as episode's cover on Spotify. This is much faster of course, but the image is not as pretty because I have been creating the graphic for each episode on canva (something simple with logo and title of episode). I wanted to hear how are you distributing your podcast on YouTube? Is there any known advantage in pushing episodes out with RSS in terms of searchability of podcasts, in addition to the time saved?
