I'm going to ventilate my basement workshop to the garage to remove fumes and dust. Should my duct work be on the intake side or the exhaust side?

It is usually against code to have shared air between a garage and living area in the US. Check code before continuing. You might lose your garage!

If your house is conditioned you're going to lose a lot of heated/cooled air by doing this also

Is the choice between having the fan in the garage vs the basement? Then noise would be a factor. Where will your filter be? Any duct before a filter would be subject to dust buildup. Are the fumes and dust fairly localized in the workshop? Perhaps a hood and duct would work best. I’m no expert, those are just my initial thoughts.

If it is an attached garage which I imagine it is, you can't have a duct through the fire wall that is open to the garage. Also you could be negative drafting the water heater and furnace which is really bad news.

And increase the pressure in the garage forcing that air into the house.

If the fumes are flammable, look into explosion-proof fans, and don't vent it into the garage.

You could run the duct thru the garage to exterior wall and terminate it there.

I think this is generally just a bad idea. Vent straight outside if you must.

I’d look at doing a DIY filter with 2” HVAC filters and a big box fan.

That's what I'm leaning towards. I just need to get after it.
