I use Bitwarden on Linux, macOS, and iOS. It works fine; you may need to sync by clicking a button, and I use AppImages on Linux and I think I need to manually download updated images, but otherwise it's free and open source, the pricing reflects hosting and development costs. I think Bitwarden also supports 2FA.

I tried 1Password and switched halfway to Bitwarden; I think there's a quant firm that reviewed password managers and recommended Bitwarden, which I trusted more than those consumer-grade sites.
