Wedding coordinator is suggesting things we didn't necessarily want?

My fiance and I are having a small-ish wedding (35-40ppl) with close family and friends at the end of September. We almost decided to elope, but he's the first of his siblings to get married, and we knew his parents would want some kind of family celebration -- which is totally fair, no issue with that!

Our main goal was to find a beautiful restaurant venue with private dining space, so that the venue, food, alcohol, service, linens, tableware, setup, cleanup, etc., was all included. It's mostly just a fancy dinner party, so we aren't having bridesmaids/groomsmen, DJ/dancing, or things like a bouquet toss, etc. We'll have a mariachi band for cocktail hour and just background playlists for dinner and mingling afterwards. Our only other vendors are photographer and floral (and tbh, we only hired the day-of coordinator because the venue required it).

We had a call yesterday to confirm the timeline with the day-of coordinator and she seemed surprised at some of the things we weren't including, and made some suggestions. Part of me is like, whatever, it's our party, but I also trust her opinion on how to make things flow naturally. I'm just wondering if these are really things that are going to make a difference?

• We're planning kind of a split cocktail hour with welcome drinks 5-5:30, ~15-minute ceremony, then cocktail hour with passed hors d'oeuvres until 6:45. She seemed to think it was weird that we'd just be around the whole time, and not do a walk down the aisle for the ceremony, and then we'd just hang out for cocktail hour and join dinner, rather than some big couples entrance. Is this that weird?
• We have a few friends/family giving speeches, which we were planning to have at the beginning of dinner once folks sit down (it's table-service, not buffet). She suggested doing these after dinner instead.
• We are having a cake cutting after dinner. Since we're not having a DJ or other dancing, we weren't planning on having a "first dance," but she suggested it's a nice way to transition from dinner to after-dinner mingling. It seems weird to me that we'd have a first dance but no other dancing?
• We weren't planning on giving a thank you speech ourselves, but she suggested that it's nice to have. I don't actually think I've seen this at many weddings?
• So the after dinner timeline she's suggesting is basically: cake cutting > first dance while cake is being served > family & friends speeches > thank you speech

Anyway, like I said, I'm not really opposed to any of these ideas. I guess the TL;DR questions -- Is it weird to not have a walk down the aisle or grand entrance at dinner? Is it weird to have a "first dance" if there's no other dancing? Is a thank you speech necessary?
