Podcast audio usually needs the same handful of fixes regardless of the recording setup: less rumble, less boxiness, more presence.
Cut the low band a few dB to reduce desk bumps and room rumble, pull back the low-mid band slightly if the voice sounds boxy, and add a small boost in the high-mid band for clarity that carries through phone speakers and earbuds alike.
Most podcast listeners use phone speakers, earbuds, or car audio — none of which reproduce deep bass well. After EQing here, it's worth a quick listen on an actual phone speaker to confirm the voice still sounds clear on the devices your audience will actually use.
