I have a basic home server running Debian 11, which I am using to self-host a few things. I would like to set it up, so that it does not run during the night. Basically, I am doing this out of noise and power management considerations.

I have considered sending it to suspend or hibernate mode and then awakening it. However, I am unsure whether this is a good way to go about it. I have also considered turning it off, but I am unsure how I can awaken it from that state (perhaps BIOS?)

Hence, my question is what is the most efficient and simple way to accomplish this. In addition, if I do go via suspend or hybernate route, how can I do it on a schedule?

For changing the state of the machine while it is on, cron jobs will do the trick. For bringing the machine back up at a scheduled time, you'll need a separate device for that. Wake-on-LAN is a useful way to do this, assuming the machine's BIOS/EFI supports it. Some routers have configuration options for scheduling Wake-on-LAN to particular hosts at particular times. Another option is a small device that's always on and can push the WOL packets to the machine at a scheduled time, like your phone.

I poked around for an Android app that could send WOL packets, and found this one:

Schedule automatic trigger of Wake on LAN packets, single time or recurrent (premimum feature)

However, it looks like you'll have to pay for the app as that bit is a premium feature.
