I would suggest to start simple.
Dashboard and Integration / devices / automations, etc, are really an intricated topic.
You should first integrate all your devices / scripts / automation mode before finalising your dashboard.
That said, you need a dashboard to interract with your devices and integrations…
To my knowledge, appart from the default dashboard, there is no “pre built” dashboard.
Thus if you want a customized one, you have to built it.
I would suggest to start with basic cards and once your HA installation is stable (all devices added, all automation made) you can start to refine the dashboard.
There are many examples around. But if you want to build a nice dashboard, while staying relatively away from the yaml (at least at the begining) I would suggest to take a look to the mushroom family of card that offer for almost all entities a very nice looking dashboard with minimal knowledge needed.
