Subway FTW, fits in your budget and is a pretty capable bike, more like an MTB than a Hybrid I suppose but maybe that’s a good thing,
it’s also worth considering accessories too, my Dad’s well in his 60’s has ridden MTBs with me since the 80’s, Road bikes before that since the 60’s but his general approach to cycling has become quite pragmatic over the last decade or so:
He goes off road less these days, He won’t ride a bike without a frame fit pump, and spare tubes & tools in a frame or bar bag, Also He much prefers riding a bike with guards (Full Guards ideally) and He’s convinced that more motorists are trying to kill him so I added a few bits of reflective tape to his bike in useful spots, fitted a couple of blinky rear LEDs and got him a Yellow Hi-Viz which he wears (But Seldom dons a helmet)…
The bits to go with the bike are handy, as they can be wrapped up as separate little pressies from any Grandchildren…
