Depends what you mean by 'floor spots'.

If it's a singaround, it's only one song at a time usually, and although you *can* sing anything you want to - and if you're only just starting out, you may need to do that - once you've got a bit of a repertoire, it's a good idea to try to provide some sort of contrast to what has been sung immediately before. Thus you're helping the singaround to function well, and it helps to keep people's attention. When you start out singing, singarounds are probably one of the easiest places to begin, and you will usually find terrific encouragement from all participants.

If you're in the South East, try going to Broadstairs Folk Week (7th -14th August), even if it's only for the odd day or two. We run the singarounds in the Sailing Club every evening, and you'd be very welcome. There are also other opportunities to sing there. Website is here

If you're talking about a two or three-song spot, try to build that set, so that there are contrasts within it - of tempo, of mood, of subject matter, of accompaniment - if you have any choice in that matter - and if you can, perhaps find ways to link those songs in your introductions. It will also help you to learn to build longer sets, if you're thinking of actually doing gigs.

Which is another point, of course. In singarounds/sessions, people don't necessarily expect, or even want, introductions, but when you're doing a spot, it's good to introduce the songs in some way. (See the thread about introductions for more detail.)

If the songs are important to you, it's probably wise to find places to sing where people actually want to listen, rather than talk over you - I'm not convinced that avoiding folk clubs is the way to do that!

Many of the other suggestions made are what I would say, too: practice so that you *learn* your songs; sing to the wall opposite you (it helps you to project); fix the right pitch (and don't be tempted to sing higher because it's noisy - in a pub session for instance, it's so easy to do!); make the song your own, not a carbon copy of someone else's interpretation of it; listen to lots of good singers (define 'good' - only you can decide what you think is so!); find out about singing and voice production techniques; but most importantly, love the songs and enjoy singing them.
