Matching this with your alsa-info, we can see that 'Mic Jack' corresponds to 0x1b and 'Mic Jack', index=1 corresponds to 0x1a.
Hence you could try turning pin 0x1a to "not connected" in hda-jack-retask. (I don't know how/if hda-jack-retask is packaged in Fedora, but it is part of alsa-tools.)
If this resolves your problem, we could then try making that the default in upcoming kernels, but the question is we really dare to do that, without clear confirmation that 0x1a is actually useless. In current state it's a bit buggy, but if the headphone jack is actually a headset jack turning that off would make the headset mic go from "needs manual adjustment to work" to "completely unusuable".
So that adjustment allows the internal microphone to be useable. However the mic in jack is now completely unusable. With a headset or a plain microphone.
Thoughts?
