Since you’re asking for opinions; you’re over thinking it. You can verify you meet R-ATP minimums so pick a regional that fits your needs and apply. As mentioned, be patient because all of them currently have a surplus of FOs. Good luck.

EDIT: You would be competitive for a Part 135 position if you found one close to you and it offered a quicker path back into the industry. But I would say waiting a few months for a regional position would be a better option.
