Is this setup overkill?

Dear people that knows more than me on this subject.

We are planing to install a network infrastructure in a real-estate with about 12 rooms. We got a suggestion from a networking firm with the following setup:

1 x Meraki MX84 Router

3x Meraki M5120-BLP 1G 8x GigE 67W Pow Switch

1x Meraki MR46 Wi-fi indoor AP

10x Meraki MR36 wi-fi 6 indoor AP

This would cost us about 8 647 dollars.

Is this to advanced for a infrastructure used mainly for the occasional surfing and in the future for 20 person LAN?

Could you recommend a more suitable brand/setup.

We really would like to lower the price so we can buy other cool stuff but we also want a decent infrastructure.

All help would be appreciated.

Cheers.
