New Home Construction

[BigC0625]

I am soon starting a new home construction and I want to get the best possible WiFi signal going through my house as possible and I am looking for suggestions or to see if what I have planned is simply overkill.

House is a 2 story with 1300 Sq Ft on the main and 1500 on the 2nd floor.  No basement just a crawl space.
I was looking at Ubiquiti UniFi systems and I think I found a list of items I would ultimately like to go with but the price is creeping up there and I am wondering if it is overkill or not.  I want seamless network connection no matter where I am in the house and even just slightly outside.

Here is my thoughts:
Dream Machine Pro with Switch 16 POE in the garage or home office as my base
Access Point nanoHD on the main floor in the kitchen/living room area
Access Point nanoHD on the 2nd floor in the hall way, centre of all bedrooms
Access Point-In Wall in my office - this is for a stronger connection in there plus it gives me 4 LAN ports to hard wire in my work PC and my personal Mac Mini

Access Point Beacon in my garage so I can have a good strong signal to my SmokeFire bbq that has WiFi

The other items are where the Switch 16 POE come into play
Doorbell
Interior cameras x 5
Exterior cameras x 3 
All of which are POE and feed back to the internal NVR in the Dream Machine

So am I overkilling my wireless network in the house?  I've never used UniFi products so I have 0 experience with them so I am looking for feedback from someone who has hopefully used them before.

Thanks in advance

No, I don't think it's overkill, but I may not be the best judge (this is all in a ~3,000 sq ft ranch home): 

 

 

I'm pretty meh on UniFi products in general.  They're slick, but honestly IME they suck for compatibility, once you're in the ecosystem things like cameras are super expensive, and performance is lackluster ... all in all, I'd rather go with someone else if I have a choice.  The trouble lately is that there are very few good alternatives to the Dream Machine Pro for good edge VPN security router, let alone one that's also a NVR - Cisco EOS'd their RV line a few weeks ago, Netgear's been out of that market for ages, you really end up with pfSense, MicroTik or Sophos.

 

One piece of rather specific advice though: unless you're using Cisco, HPE Aruba, or Rukus, keep all of your WAPs in the same basic performance category, or it'll cause roaming issues.  I think having a WAP in the office is actually a great idea, I have a WAP and then 10 network drops as well for my spouse and I, but get something similar to the indoor ones - same for the garage WAP.  I ended up using 2 stream versions of my larger 3 stream WAPs for my garage and basement coverage.
