Delete forward is Fn + delete, Home is Fn + up. It's not a specific key, obviously, but all those keys don't fit on a laptop. However, if you plug in your own keyboard I'm sure they'll be recognized.

My experience is that the only apps that use actual Ctrl on macOS are GTK apps, like Inkscape, and terminal apps (because Ctrl-C should be quite different from activating the menu item corresponding to the Cmd-C shortcut). Unfortunately, if you use non-native apps, you're going to get a non-native experience.
