I grow "Polka" raspberries which - despite being 'autumn fruiting' - have actually been producing small amounts of fruit for 2 or 3 weeks already and are now starting to fruit heavily - I can pick a small bowlful every day. They will continue producing fruit until the first frosts.
When they've finished fruiting all canes are simply cut to the ground - no worrying about which to cut and which to tie in for next year. The birds leave the raspberries alone (lots of other things for them at this time of year) - so no need for netting - and the stems only need to be contained when they start getting a bit floppy. Summer fruiters need a much sturdier permanent support system.
I would therefore recommend autumn fruiting raspberries over summer fruiters every time. You'll have lots of strawberries earlier in the summer anyway.
I have 4 canes which were planted last spring. They have already filled a space 1m x 3.5m. They will produce more than enough berries for my OH and me to enjoy fresh, as puree, as jam and stored in the freezer. 10 canes are almost certainly too many unless you have a big plot. My 4 canes are already starting to put out runners that are popping up a few feet away from the parent plant.
Clari is right that you could try to grow different varieties to stagger fruiting but you should not plant summer fruiters within 2m of autumn fruiters. The 2 types have different pruning regimes - and if you end up with a forest of new canes it can be difficult to tell which ones belong to which plant and which pruning regime to follow.
