For a desktop environment, I suggest xfce or lxde. They're very lightweight. As for the distro, all the ones you mentioned are Ubuntu-based. Even though there are some lightweight Ubuntu-based distros, like Zorin and Bodhi, you can do better. I'd suggest going for something lighter, such as the Arch-based EndeavourOS (xcfe is the default DE so it's very well-supported).
Now, if you want something even more lightweight that's still Debian-based like Ubuntu, Mint et al., take a look at BunsenLabs Linux. It's blazing fast, extremely light and very user-friendly. It doesn't use a traditional desktop environment. Instead, it uses the Openbox window manager, which requires much less resources - especially RAM, which seems like it'll be the bottleneck on your laptop.
