Whichever broadband provider you're considering using, it's worth remembering that higher speeds don't necessarily mean that you'll be any better off.
I'm still using a (non-fibre) ADSL 2+ broadband connection, which gives me a speed of about 10 Mbps. That's perfectly good enough for me to stream internet TV services, while surfing the net at the same time. (I don't download very large files, such as movies). If I paid more to get, say, 100 Mbps (or even 1000 Mbps) I would gain absolutely nothing from doing so, other than a bigger hole in my bank balance.
Fast broadband speeds are great for people who frequently download massive files, or for households where there are several teenagers all streaming video services simultaneously, at the same time that Mum is using Zoom to contact Granny and Dad is playing Fornite. However they're totally unnecessary for many people. Please don't let broadband companies con you into thinking that you actually need faster broadband services. The vast majority of people don't and they're simply throwing their money away when they sign up for such services.
