you find your best info in the conifer world finding and using the proper latin name .... if a website cant be bothered with using it.. i wouldnt trust them ....

i took your common name to the search and found this: Taxus cuspidata 'Nova'

you can take it from there ...

conifers are trees.. and they prefer full sun .. and that is where you will get your best annual growth rate ...

many.. like yews.. TOLERATE shade.. but your annual growth is going to slow down as shade increases ...

first .... a pic of your spot would get you best suggestions ..

second ... how many hours of sun.. during what parts of the day .. will give us more info to work with ... e.g. a few hours at dawn isnt much sun ....

and when asking about a plant suggestion.. always include your location.. big city name ... zone is not good enough ...

to find the best plant.. you may have to shop outside of bigbox offerings ...

Fast for a yew is still always slow for a tree. So if your concern is it getting close to the power lines some day that day is going to be a long time coming. In fact unless you are considering specimens that are already large enough to provide adequate relief you may even be waiting some years for that latter condition to be achieved.
