Congrats!! Off the bat, from my recent build, that chlorinator will not produce when you run your variable speed pump on low circulation rpms. If you can ditch it, get a salt water chlorine generator. If you feel you want a tab fed chlorinator (not advised), get one for low flow systems.
As for us, the tanning ledge was one of the most wanted, highlighted, features before build. Now that we are using the pool, it's the one thing we wish we had not done. Useless but for taking up good swim and play area. Not trying to sway you, just for consideration and to think through, but your ledge and steps take up 25% of your pool.
