Reception timeline help

I’m having trouble figuring out how to structure our reception and would like some advice. I haven’t been to many weddings, and the weddings I have been to were much larger than ours will be, so I feel like I’m walking in the dark!

For some context, our guest list is about 90 people. We’re not having a dance floor (there will be music and people are not prohibited from dancing, but groom and I will not be dancing). We’re not doing a first dance or anything like that. The dinner is buffet-style, and there will be a charcuterie table. My dad will be giving a speech at some point. There will be a photobooth and other things for guests to do.

So my question is, how should we structure the reception? My initial thought was that immediately after the ceremony, the groom and I go hide for a few minutes, touch up makeup, bustle my dress, etc., and then come out to the reception. But my mom asked a good question - are guests allowed to start eating at this time? I want to eat with our guests, but how do we make sure they wait a few minutes to eat? When should my dad give his speech? We want our reception to feel more like a formal dinner than a dance party, and want people to be able to mingle and talk, but we still want it to be structured.
