I usually use https://www.justwatch.com/ca/new to find what service a movie is on. US: https://www.justwatch.com/us/new and other countries are linked on their homepage at the bottom. Some minor Stylish/uBlock rules:

    .consent-banner { display: none; }
    ion-tab[tab="new"] .content-header { display: none; }
    ion-tab[tab="popular"] .content-header { display: none; }
