3/ The Guardian
This is the only online newspaper I still actually give money to. It's not paywalled, but their demand for donations is pretty aggressive.
It has a centre-left bias, but it's hard reporting arm is pretty scrupulous and easily identified. You can quickly see whether the post is reportage, analysis or opinion. This is helpful.
They also have fairly good global coverage, but tend to be Westerncentric. It will also let you sort by region.
