You really should try to make the drivers constant current drivers: I used to do this with TI parts, but they've been out of stock for over a year.
The TLC5916N drivers are shift registers with constant current drivers attached - great for this sort of thing. The Numitron clocks I made are also NTP/WiFi enabled and based on an ESP8266, with linear digit dimming and a whole bunch of other things (motion sensor, NeoPixel backlights etc). The ESP32 is a great platform. Absolutely love working with it, but it's a bit overkill for this.
