I have a 4 bay Synology, so let’s say I’m an infant self-hoster. It’s running Synology Hybrid Raid, which can protect against a single drive failure. Even if the whole thing goes belly up, I should (painfully) be able to recover my data.

…Unless I have a fire or some other catastrophic event happen. Is there a good strategy to mitigate these risks? I am an officer 365 subscriber (yeah yeah), so the truly important stuff on the NAS, like culled photos, are also on OneDrive.

If heavy duty means “lets you carry more weight in your bed and tow more” do not do it unless you actually have weight in your bed or tow a lot. To do this, the springs have a higher spring rate which makes the ride very hard unless you’re loaded.
