FWIW, I went from gmail -> protonmail -> fastmail, and have been very happy with fastmail.
protonmail is great as a secure disposable email, but as a go-to daily email service I found it too difficult to manage. Hard to use other email clients due to requiring this bridge, and their mobile apps and web guis are just not up-to-par with other offerings. Being able to use any frontend on mobile (and not deal with complicated proxy setups) was my biggest issue.
Using a custom domain has made the switches easier, as I don't have to tell anyone to update their contacts or worry about forwarding. Just exporting/importing, change some MX records, and I can switch providers any time.
I did the same thing. Custom domain with Protonmail. Ended up frustrated that I couldn't set up forwarding rules and alike. I realised I didn't need the privacy as much as I needed features.
Swapping from Protonmail to Fastmail was super easy. Exported all my email, imported into Fastmail, and swapped over the DNS records. Took me a couple of hours in between other tasks.
