Their other services such as Calendar and VPN have been making big strides in the past year or two as well. Even just in the past couple months the quality improvement on the VPN has been visible (speed, better reliability on streaming services).
I can only second Posteo. Using their services for years now, I can confirm that Posteo is caring about security, data protection and the environment (using green energy). Also you do not need to provide your mobile-phone number or personal information and you can use standard OTP apps to secure the weblogin when you want to use 2-Factor.
I am using several accounts shared between Thunderbird on Desktop and K-9 on Android.
The only issues I have is, when sending to some US providers that still do not have TLS ("Transportwegesicherung") implemented. In this case I have to manually deactivate the "TLS-Versand-Garantie"-option in Posteo settings, before the email can be send. Happens twice a year or so.
Maybe the Posteo suggestion gets downvoted, because their mail services indeed cost money (instead of scanning your communication and selling your data),. But I find 1€ per account per month a good deal for what you get.

Proton Mail, Tutanota or Skiff should be good alternatives for you. Avoid any e-mail provider without EE2E and zero knowledge architecture.
I currently have an account on all three, but my daily is Skiff.
More important than e-mail provider to control spam is to use a unique e-mail address for each account you own. That could be attainable using e-mail aliases or e-mail forwarding services. Look up Simple Login, AnonAddy or even DuckDuckGo E-mail Protection for more information. Putting it simple, you create a different alias for each account. They all forward to your main e-mail inbox under different aliases. If needed, you can cancel the aliases thus ending spam from that origin.
I find it a very effective technique and my inbox is always pristine.
