Give octopi launcher a try. It's the best one I tried so far.
E/os reports 0 trackers.
Personally, I use mu launcher It's minimalistic and uses gestures instead of icons
I like lawnchair a lot. Not having news/AI crap constantly loading is defenitaly a plus for battarty.
There's some knockoff/divided forks, here's the version I use.

Additionally, NetGaurd is great for locking down what has internet/cell access. It uses VPN, so if you already use that it won't work, for only 1 VPN can run at a time.
Similar to NetGuard there is Tracker Control. It also uses the VPN "slot" but it can additionally run a wireguard tunnel itself now. So you can combine access control, adblocking on DNS level and actual vpn.

Samsung OneUI collects telemetry which they use for ad targeting and sharing with third parties along with other uses. They've also had multiple leaks in their software adjacent to OneUi.
It sure could make a difference. Another option would be to get an app that lets you choose which apps are allowed internet access, such as NetGuard: https://github.com/M66B/NetGuard
I pretty happy with this: https://f-droid.org/packages/com.eblan.launcher/ It have all i need, also double click to lock screen. No need to use any hardware buttons. Also easy on battery and have enough of customisation.
Just be aware that the double tap to lock feature requires elevated permissions, which may compromise security. Whether or not that matters to you depends on your threat level.
I use fdroid open source app to have more security. Apps from google play much more unsecure. It's not about elevated rights! One of google lie.
