If you're really worried (and have the resources), you could have one computer/device for your at home wifi, banking, work and email (plus a few other trusted sites) ONLY, and another device that you use for browsing random websites, take with you and use public wifi, go on holidays with etc (but that you don't access your email with).
So you have one more safe and protected device for accessing work/email/banking and so on, and another device that you are a bit more open with and can visit other websites as this computer/device has zero or limited info of value on it.
This won't completely reduce the risk (particularly if you're clicking on links you shouldn't in your email), but so many stories seem to relate to people hooking up to public wifi that actually taps into your system and takes your personal information, installs a keylogger for your passwords etc. Or visiting a website that installs malware because you clicked a link you shouldn't.
Also maybe have a think about trying out Brave browser - you'll be supporting a crypto project, which may also reduce your risk of (accidentally) clicking ads you shouldn't since they'll be removed from the webpage.
