Each plan connects to the networks listed on its page, so you choose your carrier before you buy. Coverage varies by area: a listed network does not guarantee signal everywhere.
Not right now. Tokyo Metro's own site says its free Wi-Fi service is currently suspended due to equipment upgrades, so don't plan on station Wi-Fi on lines such as the Ginza or Marunouchi. Use mobile data for maps and transfer times, and if you were counting on Wi-Fi to download your eSIM, install it at home or at your hotel instead.
