Core switches recommendation

Hi,

I need some advice here. We need to buy a core for a remote branch. They currently have 1 stack of 6X 2960-X-48TS-L in the MDF. This stack is connected to another stack (2X 2960-X) in IDF-1. IDF-1 is then connected to the last stack (2X 2960-X) in IDF-2. The MDF is connected to Meraki MX100 where the L3 routing is happening.

The final result I want is to have 3 stacks of 2960-X (IDF-1, IDF-2 and 1 in the MDF) connected to a new core that we will buy. I will run fiber from IDF-2 to MDF and the L3 routing will happen at the core. The core will in turn connect via a transit VLAN to the upstream MX100.

Here are some stats about the network:

36 APs,

1 Wi-Fi VLAN (100 clients)

1 Office VLAN (120 clients)

1 Warehouse Office VLAN (100 clients)

1 MGMT VLAN (APs, Switches, etc)

Clients are using 10-15Gb on average every day and network usage is between 100 and 160Mb/s.

It's a warehouse some most of the Wi-Fi clients are RF scanners, mobile printers, etc. All our services are in 2 DCs and they talk to them via SD-WAN. I was wondering what core switch should we buy (it has to be Cisco, DNA/ISE compatible).

I've only been in networking for only 6 months now so let me know your thoughts and any design recommendations are welcomed.

Thank you!
