I have the CompTIA A+, Should I get the CCNA, Security+ or Network+. Goal is to become a network admin

Hey everyone, I haven't landed my first tech role but I know it's coming. I have the CompTIA A+ and my mentor told me I could get a datacenter job. I want to be an all around IT specialist meaning I want to configure and troubleshoot hardware, cabling, etc. My main goal is to become a network admin for a big environment like a school, or big company. I am really interested in security, operating systems, privacy, anonymity. I'm going to be doing a home Lab where I create a Home Network with a super hardened surface. My main goal is to learn how to create a from the bottom up, like a domain, create emails using spam filter, configure accounts permission's, workgroups etc. and make them completely hardened. So I mean like using Tacacs+ on all equipment, 802.1x WPA , with only certificates for authorized individuals, MDM, etc. I want to set up, configure the hardware, configure the domains, accounts, network security like secure dns, internet proxies like the cisco web appliance, Vpns, network segmentation for no single point of failure etc.

What certification should I get next and what route should I take to become this.
