Do I need 10GbE for my office network?

Only at the switch-to-switch and switch-to-server links. Most workstations don't saturate 1 GbE. Server-to-switch and switch-to-switch upgrades to 10GbE deliver real improvement. Workstation 1 GbE is fine until you do heavy file transfer / video editing.

SFP+ or 10GBASE-T for new deployments?

SFP+ for new builds — lower latency, lower power, more flexible (swap optics for different distances). 10GBASE-T only when you have existing Cat6a copper plant you must reuse.

How much do refurbished 10GbE switches cost?

Entry (12-port SFP+): $300-500. Mid-market (24-port mixed): $1,000-2,000. Enterprise (48-port): $2,500-5,000. Top-tier (Catalyst 9300X / Aruba CX 8400): $5,000-15,000.

Will a 10GbE switch interoperate with 25GbE?

Generally yes via SFP28 ports — most modern 25GbE switches negotiate down to 10GbE on SFP+ links. Not vice-versa: 10GbE SFP+ slots cannot run at 25GbE.
