the biggest issue is the livestock and plants in the tank. some plants and fish like it on the warm side (discus, rams, cardinals, etc) like the water 80+, and there are specific "plant packs" from different online vendors that offer plants that do well in warmer water. other plants and fish like it "cold", like goldfish, minnows, certain loaches, etc... they need plants that can thrive in cooler water temps. however, *most* planted aquariums are in the middle ground of a "tropical" body of water, somewhere in the range of 75-80F, and *most* of the plants popular in the hobby do well in these condition, as well as *most* of the fish you'll want to keep excluding the ones listed above. Even those fish *can* do well in the middle range temps as long as the other conditions are to their liking (O2 sat, etc). Goldfish thrive in cooler water, but plenty of people keep them in warmer tanks with no problems. Discus are most comfortable in very warm water, but plenty of people keep them in planted tanks around 80F without major consequences (i would suggest very frequent water changes and turning the heater up if they show signs of stress, however). With the plants and fish you've listed, a tank in the range of 75-80F should be just fine. Tetras, plecos, and angels are from warmer waters in South America, and wouldn't be hurt by water in the 80-82F range in most cases (there are cooler fast moving streams where many tetras are found, so it depends on the species). Your plants won't care too much from 75-80F.
