My current employer is all open-office, but also very remote friendly. I live hundreds of miles away so I work remote from my home office, but I've spent a few odd weeks in the office and the environment is actually pretty good for getting stuff done.
That said, remote-friendliness is something that's hard to adjust a company's culture to. I've found that heavy use of Slack and the right personalities can lead to a very productive and the sort of spontaneous sync-ups that are somewhat easier to happen in a physical office.
Ultimately the real test is whether your company's culture fits with your company's offices, and whether you fit into that culture.
