In the UK, they start on 125s. I returned to biking with a 250 and I kept it for 11 years of very contented regular use (until a forced change - to my 500 Rebel). I did add a more powerful bike to the stable during those years (now a Yamaha MT-07). Choice depends partly on how you will use a bike. A 300 will, for example, restrict your overtaking possibilities (the 500 to some extent too), but I contented myself with going with the flow - probably for the best in your case in your early years. If you are riding the twisties, greater power is still not a requirement. My choice betwen the 300 and the 500, depended on my preference for twin cylinder engines rather than singles. But that issue is unlikely to impinge upon you for a while. My pleasure from motocycling is derived from motion, the terrain and the freedom. Any bike would do really. I've even been admiring the Honda C125 (thoughfor my lounge really!).
Just do it! (I did: 2017 Rebel 500; 2014 MT-07)
