I agree this way is difficult to help you catch truly remote-first job, as requirement of sitting butt in an office contradicts it.

I recommend screening company with Glassdoor (WFH hints etc.) and at interview asking about communication/collaboration tools in use, remote teams etc.

Nowadays there is a large middle ground of companies which have globaly distributed offices. They may ask you to show up for some initial period to gain trust and mix into culture - definitely important for a long-term cooperation. Afterwards switching to remote is like relocating to different office but staying in the same project, which is pretty common practice. Tested myself several times.
