I'm currently managing a network with a single large /21 IP address pool for both wired and wireless users, and I'm looking to split it into several /24 VLANs to reduce broadcast traffic. I know resource access is primarily granted through RBAC rules in our firewall, and we use a Windows server for DHCP. I'm wondering if there's a way to set up multiple /24 subnets under one VLAN or how I should properly handle this situation.

You can't really have multiple scopes on the same VLAN, so it won't work the way you're thinking. To break up your broadcast domains, you'll need to set up separate VLANs for each /24 subnet. You should also consider using DHCP Helper IP addresses in your firewall to manage the DHCP requests from different VLANs effectively. This way, each VLAN will maintain a single broadcast domain without issues.
Got it, but how do I logically assign users to these different scopes? What's the setup like for an SSID if I want users to access multiple VLANs and keep them balanced across subnets?
