OLED and TFT screens design approach

I currently have the OLED (2) and the TFT screen (3) working in the dash
The OLED is driven by an UNO and getting CanBus data
The TFT is driven by a DUE and currently analog maps fuel level but will be sharing CanBus data going forward

I am wanting to change to add another TFT screen and also get CanBus data and basically be a real time Tacho with a sweeping needle and a digital show of RPM

I am happy enough to completely change hardware and design I am just not sure if arduino is the best way to proceed in expanding this project

I am thinking I need to create a central processing of data (mini ECU technically) and then just send to the screens (hdmi for example)

Any advice appreciated

Investigate NodeRED running on a Raspberry Pi. The Linux environment is nimble, you can control it remotely (SSH) and NodeRED will manage the webserver that you get for "free."

Integration is diverse and flows have properties for smoothing, averaging, math, etc,

For example: Serial output directly into NodeRED - Arduino for STM32 (stm32duino.com)
