One thing I will add is that there is an abundance of insurance in-house jobs now, even in light of the pandemic. Seeing as how you are a mid-level Associate and would have a year's worth of in-house experience at an insurance company, I do not think you will have much trouble at all finding another insurance law job either at a firm or in-house department.
This is great advice. I know a few colleagues who did a one-year secondment at a client (after the client approached the firm) and then returned to private practice. Some left for an in-house job (either at the same company or a different one) fairly soon after returning to the firm, but they had that as a safety net.
