Is there any advantage to using a 5 x 7 enlarger for 4 x 5 negatives along with a 180 mm or 210 mm enlarging lens? (I will never be enlarging 5 x 7 negatives by the way.)

Will the bigger cold light head of the 5 x 7 enlarger reduce the amount of edge burning required on prints made from a 4 x 5 negative and will it cover the 4 x 5 negative better than the typical 4 x 5 light source?

Will a longer focal length enlarging lens, like a 180 mm or 210 mm, produce sharper prints than a 150 mm enlarger lens? (The magnification rations will be between 3x and 3.5x the linear dimensions of the film plane to produce prints no bigger than about 13 x 16.5 inches using Tri-X film.)

Thanks in advance for your help.
