IC card/train tickets for 1 week in Japan

Here is my travel plan in Japan.

– Landing in Kansai Airport (KIX)

– From KIX, taking the train to Kyoto Main Station, then taking subway to hotel in Kyoto

– Sightseeing in Kyoto

– From hotel in Kyoto, taking subway to Kyoto main station, then taking Shinkansen to Tokyo Main Station, then taking subway to hotel in Shinjuku

– Sightseeing in Tokyo,

– From hotel in Tokyo, taking subway to Haneda Airport

Which IC card would be best to get? PASSMO or SUICA Green on Apple Wallet?

For train ticket from KIX to Kyoto Main Station and Shinkansen ticket, should I buy them seperately on Klook or should I use the IC card?

TIA
