Changing Jobs, what to do with 401k

I (42) am changing jobs, hooray… I’ve got ~50k (I know, not enough) in a 401k, and I’m wondering what the pro’s and cons are to rolling it into an IRA v. just rolling it into my new employers 401k plan? Does it make a difference in terms of taxes/taxable income for this year? Long-term does it matter?

New employer offers 2:1 matching on 401k salary contributions, but that doesn’t include rollover stuff. I’m also pretty sure it would just be from Vanguard to Vanguard if I do go for a 401k rollover and not an IRA… tbh, I don’t even know where to start if I was gonna roll into an IRA?
