Cheap Abilities

If the ability is not listed, it means the price and thresholds are about the same across architypes and you can buy it without a position change

Offense

QBs

On Time

Convert to Pocket Passer QB (cheapest and lowest threshold)

WRs

Sure Hands

50/50

Covert to Physical Route Runner TE (cheapest and lowest threshold)

Lay Out

READ CAREFULLY

Convert to Boundary/Zone CB or Coverage Specialist Safety (cheapest and lowest threshold) when you do this you cannot go directly from WR to CB or you will lose 20 or more points to catching. Here are the position changes you need to do to not mess up WR to S/MLB to CB to HB then back to WR. I know it is complicated but you will get used to it.

Shifty

Cheapest on East/West Playmaker, but has lower thresholds on Pure Runner QBs

Most of these are only the difference of a few upgrade points but that adds up. The difference in thresholds will help you get abilities earlier. Always make sure you when you are about to switch back that your architype has not changed. This is why I always suggest waiting until the final year the player will be on your team to give them abilities, unless it is something minor like a bronze/silver ability. Getting gold or platinum too early can cause you to waste a lot of points. Keep in mind using these strategies, I would definitely consider cheesy.
