If you use the aurora store it will tell you what apps require google services. My banking app works perfectly fine though I’ve heard others don’t so your milage may vary. Calyx came preinstalled with an email app which works fine, though f-droid has dozens of foss alternatives. Calyx also came preinstalled with chromium though I switched to fennec (firefox). I believe whatsapp works though I don’t have it installed nor will I.
Not the person you asked, but I run Calyx. It has microG services to impersonate google services. It works most of the time, but I have found a few apps that straight up don’t work since microG isn’t 100% viable yet.
