Debloating Stock Android with Rikka's Shizuku (non-root)

I received a regular android phone recently. It has modern hardware which I would never buy for myself due to it’s incompatible to open bootloader/firmware. The only phone I would like to buy are Pixels either to use GrapheneOS for privacy/security or LineageOS for root privilege. However, even such a phone with stock ROM can has its use case in my hand.
