First, most modern handy talkies (what Ham's call their hand held radios) are also very solid "scanners". In so far as you can tune in to a lot of different frequencies and listen. Weather alerts, AM/FM Radio (like the kind you used to listen to in your car before spotify)... you name it. Super handy if you say, lose power and cell service.
Speaking of which, remember that cell service is heavily dependent on a number of external factors. Like the antenna's still being upright (earthquakes, tornado, hurricanes are bad). There still being power. There still being connectivity (typically fiber optic)... and most importantly - NOT being overloaded. With a Ham radio you can listen or transmit, with no other dependencies.
For more local issues, like hiking or camping. Even if you're out of cell range, your radio may very well work. A 5W handy talky can reach up to 30 miles, depending on your location (basically line of sight). If you can get to the top of a hill or mountain and get a clear view - you can get a signal out to someone. All you need to do is get on the 2-Meter Band Calling Frequency (146.520 Mhz) or the 70-Centimeter Band Calling Frequency (446.000 Mhz) and it's a safe bet someone out there is probably listening. Even better if you've looked up local repeaters in the area.
Also, the radio's are stupid cheap now. BaoFeng makes "cheap and cheerful" (nicest way to describe them) handheld units: Like a 8watt unit for $70 USD. https://www.amazon.com/BaoFeng-BF-F8HP-Two-Way-136-174Mhz-40... -- They even sell 2 packs of slightly weaker radios for $50 total. Are they the best? No. Should you splurge and get something better? Totally. Like a 10W radio that support DMR (Digital Mode) for $180 https://www.amazon.com/Radioddity-GD-AT10G-Handheld-Digital-... . But if you just want to get your ham and use it once-every year... get a $50 radio and toss it in your car or something similar. Just make sure to get alkaline batteries for them. Lithium rechargeable are nice but lose charge over time.
