Need help in network design change and in choosing switch model

Dear Experts,

We are planning to do full upgrade because the existing network devices from core to edge level switches are currently 7 year old. Because we are non-Cisco shop and would like to migrate over to Cisco/Meraki we need help.

Would you please recommend Cisco switch models that would be best suitable for us? Thanks a lot!

Environment: College campus User count - 1,500 Printers - 50 Wifi Access points - 450 Servers - Physical 8-10 (virtual many)

Current network info:

2 backbone HA switches 15 distribution switches (DL) - 10G fiber optical uplink to the core switch Around 60 edge switches (4 to 8 access switches connected to each DL. switch) - 1G fiber optic connection uplink to DL switches All switches are Allied Telesis.

Question 1: Which switch Cisco model would you recommend for the core, DL and edge level switches?

Question 2: - Is it better to get rid of DL switches and replace them with stacked edge switches or keep the existing structure (15 DL switches and stacked edge switches)?

Thank you so much with your help!
