@ocnbrze I am generally opposed to cleaner apps: they're usually more malware than anything useful, and there's very little for them to actually do.
Besides the risk of the app collecting your data and sending it home to someone, having additional storage available isn't making your phone run any better or faster. Imagine having a huge walk-in closet but you only need one small section for your entire wardrobe. What good would it do for you to install shelves to hold even more... or even knock out a wall to make it bigger? It's unused capacity - the key word being "unused".
The system cache is actually making your phone work better and faster by storing much of your phone's most commonly-used data for quick access. Generally, the only time I would recommend someone go into Android Recovery to wipe cache is after a major OS upgrade (from Android 12 to 13, for example) or if the phone is behaving erratically. Otherwise, an occasional restart of the phone is enough to get it working well again.
