Just to start off with the reports/rumors.
Russell Wilson has supposedly met with Steelers and Giants, which the Giants need a total rebuild and Wilson seems like a bad fit.
Rumors have suggested Kirk Cousins to the Falcons is likely, with the Falcons running the Rams Wide Zone like the Vikings have been doing under their current head coach, and Cousins' wife being from the Atlanta area (and where they got Married). Also, the Falcons have a freaking ton of 1st round pick weapons and a very good run blocking OL (though they're maybe not the best at pass protection, if you get the play action game going it can potentially be a great fit).
I thought about the idea, with Pete Carroll out, maybe Wilson returns to the Seahawks? But looking at Geno Smith's contract, I'm thinking that's unlikely... though Giants are in a similar situation with their starting QB (though he also has an ACL injury) so it's possible but unlikely.
I think the best potential landing spots for Wilson would be, Steelers, Raiders or Buccaneers (if they don't keep Baker Mayfield).
Under the Buccaneers scenario, Mayfield goes to the Falcons (to work with the offensive coordinator he previously worked with while on the Rams), Cousins stays with the Vikings, and Buccaneers sign Wilson. But I think Buccaneers and Mayfield are trying to work something out.
Raiders seems like a good fit, as they seem like they want a veteran to take charge, especially with the rookie head coach. To my knowledge, they haven't shown any interest in Wilson, but technically Wilson is still under contract, but has been given permission to talk with other teams, but that might be all teams outside of the division, and therefore not Raiders. Otherwise, why not just release him already? Unless they're trying to trick a team into trading for him, which has a 99.9% of failing.
I think the simple answer is the Steelers, they've shown the most interest in him, and their offense seriously struggled last year and the head coach seemed to believe it wasn't the offensive coordinator, but seemed like his arm got twisted enough that he had to let the coach go, and seemed like their offense improved once they got the 3rd string QB in.
And while I think this one is highly unlikely, I just want to throw it out there.... Wilson to the Dolphins. Dolphins are supposedly already $16 million over the cap... Tua is costing them $23 million this year and likely wants in the $50 million per year going forward... and has a history of concussions.
