Is this worth your time to worry about? Does your startup have solid runway and/or are you profitable? Do you have solid PMF? If the answer is no, and I suspect it is since you're deliberating where to host, then get back to shipping features.

To be reductionist ... I'd rather have to deal with vendor lock in a growing successful startup, then have cloud agnostic infrastructure and be out of runway.

Even then, I think people generally over-engineer this problem. I've worked at multiple unicorns who have been 'locked' in to AWS/GCP/Azure.

Think in terms of risk, and opportunity cost.
