My current job is going through a merger and I have multiple different offers, what should I choose?

Context: I am a software engineer who has been working at a company that was recently acquired. Currently make 135k. My current company is being merged into a larger parent company and there were some recent layoffs. Management has signaled these will not be the last, and there will be more next year after a 'discovery' phase where they figure out what can be integrated into the parent company's existing software and what cant. We are currently mostly working on documentation + support work instead of new features. This has resulted in me going on a job hunt.

My wife has health issues and cant work, and I am tried of looking for jobs (I've been doing interviews on and off for the past couple years now and it has been very stressful, gained 20 pounds), so I am valuing stability over anything else right now. Dont want to have to look for another job for at least a few years if possible.

I have three options:

Offer 1: 165k base salary, 15 days of PTO (100% WFH). Established non tech related company owned by private equity that is working on a new project modernizing a legacy system to Python / AWS, immediate team and manager seem really nice and fun to work with. ~20 engineers total.

Offer 1 Cons: Company has been owned by private equity for the past 7 years, has a 2.9 star on Glassdoor, mentioning lack of raises, leadership shifting priorities, and layoffs / reorgs. Also apparently the private equity is looking to make an exit to a private buyer sometime 2027. Talked to someone on the team who quit and he mentioned that part of the reason for it was that there are various issues / headaches with modernizing the legacy system.

Offer 2: 165k base salary, unlimited PTO, 3 days hybrid. Various feature / integration work in Node / AWS. Team seems nice as well. Series D unicorn / billion dollar fintech company with lots of customers. (many which are large companies). Has better glassdoor reviews with less red flags (3.7).

Offer 2 Cons: Mostly the 3 days in office, would require me to move to another city in 6 months. But thats not a huge deal for me since I just want stability and to stop the job search for at least a few years. Although the recruiter did mention that the company was looking to do an IPO in ~2 years. I asked the director about that in an interview and he said he wasn't aware of that (maybe the recruiter wasn't supposed to disclose that information lol).

Option 3: Stay at my current company and hope I can find someone that isn't looking to make an exit in the near future before I get laid off. I have gotten a few other offers over the past couple months, but they have all been early stage startups which are even more unstable.

What are y'all's thoughts?
