More appropriate way of having straight lines and adding arrow head easily
I am an academic and use straight lines and block diagrams for illustrating my methodologies. Although having a rectangle or square is super easy, it is not straightforward to create straight line or arrowhead. Please make sure these features can be used appropriately. Thanks

I can’t see what is the complexity with straight lines.
To make one, you pick the Line tool, click and drag, with Shift held if you want to to snap to 0–90–45° angles. No big difference from rectangles you say are easy enough to draw.
Arrowheads can be assigned in Stroke panel, if you enable Show Options form the panel’s menu. You also can access these in Properties panel by clicking underlined 'Stroke'.Please explain what makes it difficult for you?
