Here's the fuel system components I would recommend for you.
Fuel tank from Tanks Inc.

GPA-4 in-tank fuel pump. This is the tried and true Walbro 255, it'll support about 630 hp on a normally aspirated, gasoline engine.

You can opt not to go for the soft fuel line if you prefer hard lines. I will say that I've had EFI rated soft line under my car since 2015 and about 30,000 miles of operation. It's still in great condition. Yes it will need replacing at some point before a hard line would need replacing, but I wouldn't be afraid of it either. It's a good bit easier to work than hard line.
The fuel line kit above would be designed to utilize the FiTech or Sniper internal regulator. If you prefer an external regulator, or want to start with your fuel system now, they do offer a kit with a bypass regulator designed to work with carbs. Then, when you do the EFI unit itself, change the spring in the bypass regulator to get your pressure up to EFI required levels.
