Using 3 Monitor DP/HDMI Setup + Charging new Macbook Pro 16'' over max. 2 Cables

I want to finally switch back to a Macbook Pro after some years of using a PC. However, I do not want to give up on my setup using 3 to 4 screens.

My plan is on using the MacBook Pro 16 Inch i9 model. My screens support HDMI and Displayport 1.2 with MST/Daisy Chain. I also need Gigabit Ethernet, a USB-C Connection for an external SSD and some USB Ports for my Soundcard, Midi Piano and so on and also want to charge the laptop. I want to use for this a maximum of 2 Thunderbolt or USB-C Connectors (Which I can glue together so that I only need to plug one thing to connect or disconnect)

TL:DR -- my goal is (in short):

Connect min. 3 external HDMI or Displayport Monitors (Which Support Daisy Chaining)
Charge the Macbook Pro
Have Gigabit Ethernet and USB A Ports
Maximum of 2 Connectors
Should have good performance (so no airplay)

Idea 1: The usualy way - DisplayPort Daisy Chain/MST

Macbook => Dock => Display => Display => Display
                => USB Devices + Ethernet
        => Charger

Usually I would "just" daisy chain my DP Screens, however I've read that MacOS does not support DisplayPort MST? So it probably will not work.

Idea 2: Using 2 Thunderbolt Docks on 2 Ports

Macbook => Thunderbolt Dock => Display (via DP)
                            => Display (via Thunderbolt Adapter)
                            => USB Devices + Ethernet
        => Thunderbolt Dock => Display (via DP)
                            => Display (via Thunderbolt Adapter)
                            => Charger

the next Idea would be to use 2 Thunderbolt Docks on 2 different Ports and to connect 2 displays on each (Per dock one via DP and one via Thunderbolt adapter). However, as I want to also charge the Macbook, one of these docks must support power delivery - I havn't yet found one that supports the 100W that the new macbook pro needs. I also don't know if that would work.

Idea 3: Using 2 Thunderbolt Docks Daisy Chained

Macbook => Thunderbolt Dock => Thunderbolt Dock => Display (via tb adapter)
                                                => Display (via DP/HDMI)
                            => Display (via DP/HDMI)
                            => USB-Devices/ Ethernet
        => Charging

The most elegant solution seems to be using two thunderbolt docks in series. and then connect one display via DP on the first dock and one via DP + one via Thunderbolt on the second dock. So I can use the other Thunderbolt connector on the mac for charging.

The devices would be e.g. Elgato Thunderbolt 3 Pro Dock and WAVLINK USB C Thunderbolt 3 to Dual DisplayPort

Will one of the above work? Any other Ideas (e.g. a dock with 3 Displayport outputs that actually work with OSX)?

Caldigit TS3+ can do 87Watt charge with a firmware upgrade, my mac even at full load have not started discharging the battery with this.

Please be aware, that there are many users (including me), that has issues with external displays connected to the Macbook Pro 16" specifically. It will pin the Radeon GPU at 18watt+ and keep the laptop fans spinning around 3k rpm and 60 degrees C at idle. Apple have not responded to the issue even calling support puts your trough random loops of tests that does nothing.
