What track should I have for my DLC of my project?

My plan is:
Heart Cup:
SNES Mario Circuit 1
CT
Wii U Mario Kart Stadium
CT
Boo Cup:
GBA Broken Pier
GCN ???
Wii ???
Tour ???
Feather Cup:
SNES Ghost Valley 3
DS ???
CT
Tour New York Minute ?
and Bob-omb Cup:
N64 Wario Stadium
Wii U ???
3DS ???
DS Airship Fortress

Boo Cup
GCN Waluigi Stadium
Wii Moonview Highway
Tour Vancouver Velocity

idk very many CTGP tracks, so I can't help with those...

those mean custom tracks

It is a pain to mod Switch Lites!!! So far I've managed CTGP deluxe with emulation.

And my PC won't stop freezing or just running slow when I start it up.

Sorry I took so long to respond, but I found an old project that included banger tracks from the retro courses like:
GCN Baby Park
DS Yoshi Falls
DS Tick-Tock Clock
DS Figure-8 Circuit
Wii Grumble Volcano
Wii Moonview Highway
3DS Wario Shipyard
3DS Piranha Plant Slide
Tour Piranha Plant Pipelines

I got my models from:

(edit) I don't have the original file anymore, but I did find my sources!
