Amazon had an extra ~$10 off the Aqueon and there are same tank at Petco for the price mentioned free delivery over $35 (said on the header, not sure what might be excluded)
Of your choices, Aqueon would be my pick.
Another slightly more expensive but really nice tank is the Fluval 15G offers some very nice features like remote and adjustable lighting, hidden 3 stage filtration in back and included.
You could go with nano fish and nano Cories. Some fish to consider - Ember Tetras, Sparkling Gourami, Sundadanio Axlerodi (softer water fish) Scarlet Badis or Peacock Gudgeon, Boraras Brigittae Chili Rasboras or similar nano fish Rasboras, Neon Green Tetras.
