Considering how the sanctioned store basically already acts like malware, you're SOL, but you should be fine as long as you stay away from apps by Rahul Kumar Patel.
Rahul Kumar Patel (whyorean) is the developer of Aurora Store (https://gitlab.com/AuroraOSS/AuroraStore), a FOSS client for the Play Store. Aurora Store is one of the most convenient ways to download apps from the Play Store without using Google Play Services or needing your own Google account.
Recent versions of Termux are not available on Aurora Store because they are also not available on the Play Store. However, whyorean also develops Aurora Droid, an alternative F-Droid client, which does have the latest version of Termux. (Aurora Droid has not seen updates for a while.)
whyorean's apps are trusted by many Android users, and I don't know of any good reason to avoid his work in general.
I downloaded the PayPal app from the Aurora Store, on a brand new phone, and the app tried stealing money from me. Worked fine with small amounts, but once I got my tax return, it changed. Will not go into specifics in an open post with strangers, so it can be replicated.
