You got it. Here’s what the Flux documentation says about plated through-hole pads:
“Configuring a Pad
Configure a Pad using the Toolbar
Configuring a pad is easy with the toolbar. When a pad is selected on PCB, a toolbar shows up above it on the canvas. From there, you can change its position, size, pad type, pad shape, and hole size.
Pad Type
Modifies the type of pad to one of the following:
SMD – a surface mount pad with no drill hole.
HOLE – a drill hole with no copper.
STD – a through-hole pad. (STD stands for "Standard".)
Solder Mask Expansion
Defines the size of the opening in the solder mask relative to the pad edge…
Hole Size
Sets the size of a drill hole in the pad.
Thermal Relief
Defines how a pad connects to a fill. The Relief Connect option separates the pad from the fill and connects them with conductors… The Direct Connect option is essentially "no thermal reliefs".”

If you want, tell me the wire lead diameter and desired pad shape, and I’ll guide sizing and mask settings.
