Share everything or some

This might sound stupid but as someone who is thinking of freelancing for events at his campus, there are some things I wanna know from experienced photographer. Especially for like sports photography where burst shooting is normal.

1. Do y'all edit and share every single picture or just the ones you think looks the best out of the burst? because I always have the thought of "oh they might like Picture A more than Picture B, imma share it as well just in case so they can have options".

2. How long do you guys usually ask for the "editing period" before sharing the results with the client. I've seen a post on Thread/Twitter saying they had to wait for about 6 months for photos and videos that didn't meet their expectations given how long they had to wait. so like, what's a good duration for the "editing period" for someone who just starting out?
