I have played Fifa on the Switch and it is amazing. Graphically not as good as Ps4 but still excellent in its own way and has all the features barring Journey and a couple others.
To be honest i played Fifa more on Switch than Ps4. Has all Champions league licenses etc.
I feel Cricket 19 will be similar to The Ps4/Xb1 version unless it is Xbox one X which Ross mentioned on twitter would be different graphically. The thing with Fifa is they have been around for many years and there game is now so good and advanced that they have a different studio making the Switch version specifically. As cricket 19 is made by the same people i feel the graphics and gameplay will be pretty much identical.
Also until maybe a few years when we hopefully get more iterations of cricket, the graphics will evolve, we will then see a noticeable difference in graphics and features when compared to the Switch.
