DeGoogle Yourself

If you are technically-minded, might I suggest SpamBlocker?: https://f-droid.org/packages/spam.blocker/

It's not the most user friendly, but it provides features like:

• automatically download spam database info
• regex rules for sms
• STIR attestation
• various rules you can adjust (like accepting calls right after using a specific app [like a food delivery app], or accepting calls from contacts, etc.)

Note that if a call or SMS is "blocked", it's still stored in your call / sms logs. It just prevents alerting you

i use Carrion (f-droid); however it may not be what you are looking for.

in carrion, numbers fall into 3 categories:

• known good
• known bad
• unknown

carrion can silence the ringer, not show the call and silence the ringer, or allow the call as normal based on settings for each category.

I used to use Should I Answer. It works well but I'm not sure whether you can trust it privacy-wise.
