WMF is an ugly buggy format. Do not use it for printing. Try to avoid it.
Corel output for print is very good, but you have the risk of not having some profiles updated becouse your version is some years old.
Yes you can draw once, but in any program you choose, you need to draw an image acordingly to the ouput. Correct colors for print or correct colors for web, the amount of nodes, transparencies or grdients, and embeded images.
But for animations... I am not aware of any drawing program to animate them. It can be done via code, normally JavaScript and CSS like this:

The 2 real progrms you have to draw and print are Ilustrator and Corel, and both can export fairly decent SVG.
For simple SVG Inkscape is very good (but not that good for print).
If you are familiar with Corel I see no reason to change it, probably update it. When I need to export a "more compilant" svg, I draw it on Corel, open it on Inkscape and re-save it. It is a simple step.
