I use my laptop every day and usually finish by hibernating it. Is it safe to hibernate 24/7, or should I shut the machine down regularly? I'm mainly wondering about battery use, hardware wear, system stability, and whether Linux needs an occasional full restart.

You should still restart or shut down occasionally, especially when the system installs updates or when drivers and services start behaving strangely. A restart clears and reloads everything; hibernation can preserve problems along with your session. If you don’t need to keep your apps open, a normal shutdown is the simplest option.
Be careful not to confuse sleep with hibernation. Sleep keeps the RAM powered and can drain a significant amount of battery, while hibernation should use virtually none. Closing the lid may trigger sleep, hibernation, shutdown, or nothing at all depending on your settings.
Hibernate is basically a shutdown that saves your current RAM contents to storage first, so it uses almost no power while the laptop is off and lets you resume your session later. It shouldn’t harm the hardware, and using it every day is generally fine.
Hibernate is usually more power-efficient than sleep because it writes the session to the SSD and powers the system off completely. However, Linux hibernation can be unreliable on some hardware, so test it before depending on it. Also make sure your hibernation setup has enough swap space.
So hibernating isn’t necessarily more protective than shutting down—it mainly just preserves my open session?
